FieldForwarding hints

[Newport, Billy]

For the following map, what would the hint be:

@ForwardedField("f0->f1") // Correct?
public class Tuplator extends FlatMapBase<GenericRecord, Tuple2<Void, 
GenericRecord>>
{
     /**
     *
      */
     private static final long serialVersionUID = 4443299154253252672L;

     public Tuplator(SerializableAvroRecordBuilder avroRecordBuilder)
     {
           super(avroRecordBuilder);
     }

     @Override
     public void flatMap(GenericRecord value, Collector<Tuple2<Void, 
GenericRecord>> out) throws Exception
     {
           out.collect(new Tuple2<Void, GenericRecord>(null, value));
     }
}

Given the input is not a tuple, can I even still use hints?
